But the squad has come out on the other side of these tumultuous times, and they're better for it. Now they're dropping some major knowledge in the hopes that you'll learn from their mistakes in the above very important "PSA" pointing out "things you should (already) know."

Take Stassi Schroeder, for instance. After finding out that Kristen Doute hooked up with her then-on-again, off-again flame Jax Taylor, Stassi memorably let her onetime bestie have it in Season 2 of Vanderpump Rules. But now she realizes the error of her ways. Sort of. "If your best friend hooks up with your ex-boyfriend, keep your cool, talk it out, don't bitch slap her," Stassi advises in the above clip. "Unless she does it again."

Ladies, take note.

It certainly looks like we're seeing a new Stassi this season of Vanderpump Rules, as well as new digs, which you can check out, below.
